The G6 is available with the following communication technologies:
Integrated shut-off valve (optional) remotely controllable for end-customer contract management.
Despite being highly innovative, Domusnext® meters have passed the most stringent reliability tests, conducted by notified body and designated laboratories recognised at European level. This certifies the robustness of MeteRSit meters and the accuracy of their measurements, even at high concentrations of dust and contaminants in the gas distribution networks. The high accuracy of the measuring principle ensures the gas meter compliance with the MID (MeasuringInstruments Directive). Such micro-thermal measuring principle is also commonly used in laboratory instruments. Resistance to contaminants and dust is ensured by design.
Measurement is intrinsically compensated in temperature and independent from pressure. Measurement is displayed directly in standard cubic-meters*. The measurement technology is based on a MEMS "Micro Thermal Flow Sensing" principle. Two temperature sensors are symmetrically placed around a micro-heating element: under stopped-flow conditions, both sensors measure the same temperature. As the flow rate increases, heat is carried away from the upstream sensor towards the downstream sensor and the measured temperature difference between the two sensors is proportional to the mass flow rate.
The accuracy of measurement is not affected by changes in the chemical composition of the European distributed gases within the 2nd family groups H and L (as defined by EN 437:2003). By measuring specific gas properties, a pre-set auto-calibration process guarantees the required accuracy levels without any additional adjustment. The meter is also able to operate in air (test phase), by calibrating it self accordingly without any additional adjustment.
Management of 3 tariffs, with consumption divided into 5 daily tariff bands, which can be programmed for weekdays, weekends/public holidays and daylight saving time.
The application software can be remotely updated or locally updated via optical port in accordance with the EN 62056-21. SIM card is replaceable on location; it is accessible from the battery compartment. The meter is equipped with an Integrated high performance antenna.An external antenna is available on request..
Thanks to the static technology adopted, the meter has a very low level of noise and practically no wear . This characteristic is well appreciated in particular for domestic application.
Domusnext® meters provide an exact measurement of supplied gas in standard m3, avoiding the use of annual average temperatures and conversion factors, which inevitably lead to approximate values and errors of estimation. These errors then affect the amount billed.
